The 100 megawatt project will be three times larger than anything like it and could transform the efficiency of renewable energies. Tesla will partner with the French renewable energy firm Neoen to build it and it will be powered by the nearby Hornsdale Wind Farm.

It will ultimately supply electricity to 30,000 homes.

This will be the highest power battery system in the world by a factor of 3. Australia rocks!! https://t.co/c1DD7xtC90

"We actually insisted in the contract that we be held to the hundred days or it's free,” Musk said. “That's what we said publicly, that's what we are going to do.”

All around world, energy is lost through inefficient storage systems. Oftentimes, storage systems aren’t available and the energy produced is simply wasted. Other times, energy is leaked as it makes its way to storage or when it reaches storage.

This ends up reducing the usefulness of renewable energy and leads to a greater reliance on fossil fuels, which can, unlike renewables, can be tapped on demand to create energy.

But lithium batters aren’t flawless. The Stanford researchers found that the energy used to create and maintain these batteries often outweighs the energy that they ultimately store when paired with wind farms, which leads to a net loss of energy. When used with solar farms, there result is neutral.
